873, 873H Bobcat Loader Operation & Maintenance Manual

SAFETY INSTRUCTIONS FOR BOBCAT SKID–STEER LOADERS AND ATTACHMENTS SAFETY IS THE OPERATOR’S RESPONSIBILITY All Bobcat loaders and attachments are designed to give maximum safety, but no machine design can prevent operator error or carelessness.

The Bobcat skid–steer loader is highly maneuverable and compact. It is rugged and useful under a wide variety of conditions.

This presents an operator with hazards associated with off highway, rough terrain applications, common with Bobcat loader usage.

The Bobcat loader has an internal combustion engine with resultant heat and exhaust. All exhaust gases can kill or cause illness so use the loader with adequate ventilation. The loader has a spark arrestor exhaust system or muffler which is required for operation in certain areas.

The dealer explains the capabilities and restrictions of the Bobcat loader and attachments for each application. The dealer demonstrates the safe operation according to Bobcat instructional materials, which are also available to operators. The dealer can also identify unsafe modifications or use of unapproved attachments. The attachments and buckets are designed for a Rated Operating Capacity (some have restricted lift heights) and secure fastening to the Bobcat loader. The user must check with the dealer, or Bobcat literature, to determine safe loads of materials of specified densities for the loader–attachment combination.

The following publications and training materials provide information on the safe use and maintenance of the Bobcat loader and attachments:

• The Delivery Report is used to assure that complete instructions have been given to the new owner and that the Bobcat loader and attachment is in safe operating condition.

• The Operation & Maintenance Manual delivered with the Bobcat loader or attachment gives operating information as well

as routine maintenance and service procedures. It is a part of the machine and can be stored in a container provided inside the cab of the loader. Replacement Operation & Maintenance Manuals can be ordered from your Bobcat dealer.

• Machine signs (decals) instruct on the safe operation and care of your Bobcat loader or attachment. The signs and their locations are shown in the Operation & Maintenance Manual. Replacement signs are available from your Bobcat dealer.

• An Operator’s Handbook is fastened to the operator cab of the loader. Its brief instructions are convenient to the operator.

The Handbook is available from your dealer in an English edition or one of many other languages. See your Bobcat dealer for more information on translated versions.

• The Safety Manual delivered with the Bobcat loader gives general safety information.

• Operator Training Courses are available from your local Bobcat dealer. They provide information for safe and efficient operation of the Bobcat loader and some attachments. The courses are available in English and Spanish versions.

• Service Safety Training Courses are available from your Bobcat dealer. They provide information for safe and correct service procedures.

• See the ADDITIONAL PUBLICATIONS Page in this manual or your Bobcat dealer for Service and Parts Manuals, printed materials, videos, or training courses available. Also check the Bobcat web site www.bobcat.com

The dealer and owner/operator review the recommended uses of the product when delivered. If the owner/operator will be using the machine for a different application(s) he must ask the dealer for recommendations on the new use.

Call Before You Dig 1–888–258–0808 When you call, you will be directed to a location in your state/ city for information about buried lines (telephone, cable TV, water, sewer, gas, etc.)

• Check the rules and regulations at your location. The

rules may include an employer’s work safety requirements. Regulations may apply to local driving requirements or use of a Slow Moving Vehicle (SMV) emblem. Regulations may identify a hazard such as a utility line.

Warnings on the machine and in the manuals are for your safety. Failure to obey warnings can cause injury or death.

W–2044–1285

• HAVE TRAINING WITH ACTUAL OPERATION • Operator training must consist of a demonstration and verbal instruction. This training is given by your Bobcat dealer before the product is delivered.

873, 873H Bobcat Loader Operation & Maintenance Manual

FIRE PREVENTION The machines and some attachments have components that are at high temperatures under normal operating conditions.

The primary source of high temperatures is the engine and exhaust system. The electrical system, if damaged or incorrectly maintained, can be a source of arcs or sparks.

Flammable debris (leaves, straw, etc.) must be removed regularly. If flammable debris is allowed to accumulate, it can cause a fire hazard. Clean often to avoid this accumulation. Flammable debris in the engine compartment is a potential fire hazard.

The spark arrestor exhaust system (if equipped) is designed to control the emission of hot particles from the engine and exhaust system, but the muffler and the exhaust gases are still hot.

• Do not use the machine where exhaust, arcs, sparks or hot components can contact flammable material, explosive dust or gases.

• The operator cab, engine compartment and engine cooling system must be inspected every day and cleaned if necessary to prevent fire hazards and overheating.

• Check all electrical wiring and connections for damage. Keep the battery terminals clean and tight. Repair or replace any damaged part.

• Check fuel and hydraulic tubes, hoses and fittings for damage and leakage. Never use open flame or bare skin to check for leaks. Tighten or replace any parts that show leakage. Always clean fluid spills. Do not use gasoline or diesel fuel for cleaning parts. Use commercial nonflammable solvents.

• Do not use ether or starting fluids on any engine which has glow plugs. These starting aids can cause explosion and injure you or bystanders.

• Always clean the machine, disconnect the battery, and disconnect the wiring from the electronic controllers before welding.

Cover rubber hoses, battery and all other flammable parts. Keep a fire extinguisher near the machine when welding. Have good ventilation when grinding or welding painted parts. Wear dust mask when grinding painted parts. Toxic dust or gas can be produced.

• Stop the engine and let it cool before adding fuel. No smoking!

• Use the procedure in the Operation & Maintenance Manual for connecting the battery and for jump starting.

• Use the procedure in the Operation & Maintenance Manual for cleaning the spark arrestor muffler (if equipped).

• Know where fire extinguishers and first aid kits are located and how to use them. Fire extinguishers are available from your Bobcat dealer.

ATTACHMENTS AND BUCKETS

A

NOTE: Warranty is void if non–approved attachments are used on the Bobcat loader.

WRONG

Never use attachments or buckets which are not approved by Bobcat. Buckets and attachments for safe loads of specified densities are approved for each model.

Unapproved attachments can cause injury or death.

W–2052–0200

B–15695

The dealer can identify, for each model loader, the attachments and buckets approved by Bobcat. The buckets and attachments are approved for Rated Operating Capacity and for secure fastening to the Bob–Tach.

The Rated Operating Capacity for this loader is shown on a decal in the operator cab. (See SPECIFICATIONS Page 91)

AVOID INJURY OR DEATH Do not exceed rated operating capacity.

Excessive load can cause tipping or loss of control.

The Rated Operating Capacity is determined by using a standard dirt bucket, and material of normal density, such as dirt or dry gravel. If longer buckets are used, the load center moves forward and reduces the Rated Operating Capacity. If very dense material is loaded, the volume must be reduced to prevent overloading.

Exceeding the Rated Operating Capacity [A] can cause the following problems:

Use the correct size bucket for the type and density of material being handled. For safe handling of materials and avoiding machine damage, the attachment (or bucket) should handle a full load without going over the Rated Operating Capacity for the loader. Partial loads make steering more difficult.

TIRE MAINTENANCE

A

Wheel Nuts See SERVICE SCHEDULE Page 39 for the service interval to check the wheel nuts. The correct torque is 105–115 ft.–lbs. (142–156 Nm) torque [A].

Rotating Check the tires regularly for wear, damage and pressure.

P–10142

Inflate tires to the MAXIMUM pressure shown on the sidewall of the tire. DO NOT mix brands of tires used on the same loader.

B

I–2057–0794

Rear tires usually wear faster than front tires. To keep tire wear even, move the front tires to the rear and rear tires to the front [B].

It is important to keep the same size tires on each side of the loader. If different sizes are used, each tire will be turning at a different rate and cause excessive wear. The tread bars of all the tires must face the same direction.

Recommended tire pressure must be maintained to avoid excessive tire wear and loss of stability and handling capability. Check for the correct pressure before operating the loader.

B–09976

Mounting Tires are to be repaired only by an authorized person using the proper procedures and safety equipment.

Tires and rims must always be checked for correct size before mounting. Check rim and tire bead for damage.

Do not inflate tires above specified pressure.

Failure to use correct tire mounting procedure can cause an explosion which can result in injury or death.

W–2078–1285

The rim flange must be cleaned and free of rust.

The tire bead and rim flange must be lubricated with a rubber lubricant before mounting the tire.

Avoid excessive pressure which can rupture the tire and cause serious injury or death.

During inflation of the tire, check the tire pressure frequently to avoid over inflation.
